Tip for Junglers

Always assume an invade is coming if you don't have vision on their jungler. Use your trinket ward and ward the brush next to red/blue buff. If you don't have the ward, take one second and stand in the bush and fight the buff there. It's better to be in the bush and spot the invade instead of fighting the buff in the open and the enemy jungler is waiting in the bush to steal your buff and get a free kill.
